Think about what you think about. Do you ruminate upon the days events or do you consistently and persistently think about your dreams and how to achieve them?

Thinking about what you want sets up a flow of thought that broadens with time much the way rain water trickles into small streams that join to create small rivers which join to create larger rivers.

If you will consistently and persistently (and of course, happily) consider your dreams and how to achieve them the result will be that your dreams will become reality in much the same way the Amazon becomes the Amazon.
